How can You Update Sony Drivers?

There are numerous of common warnings and also other messages which you may get in the driver updating process, many of which I've paraphrased and listed right here together with information on how to proceed:

Windows requires a digitally signed driver: You won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue, in 64-bit versions of Windows. If you see this message, end the driver update process and locate the correct driver from the hardware maker's website.

To download and update the driver for SONY VPCF13CGX yourself (If you are a geek)

It's best to let Windows install device drivers automatically. But if Windows can't find a driver for your SONY VPCF13CGX, you can look for a driver on the manufacturer's website of SONY. Driver updates are often available in the support section of such sites.

Once you find the updated driver, follow the installation instructions on the website. Most drivers are self-installing—after you download them, you usually double-click the file to begin the installation, and then the driver installs itself on your computer. What you should know is that a wrong driver may cause system malfunctioning which you should be careful about. Download a professional driver updater or find a geek to help you.

2. Scan your computer for out-of-date drivers. Select the ones(here you should select SONY VPCF13CGX) which need to be updated and click download. Or you can just check SELECT ALL.

3. After the download process is finished, you should click SETUP to install them. That's it! Your driver for SONY VPCF13CGX has been updated. Sometimes a restart is required to put the drivers into use.
